Virpax Pharmaceuticals, Inc.

1055 Westlakes Drive, Suite 300

Berwyn, PA 19312
Attn: Chief Executive Officer

Ladies and Gentlemen,

This letter (the “Agreement”) constitutes the agreement between Spartan Capital Securities, LLC (the “Placement Agent”) and Virpax Pharmaceuticals, Inc., a Delaware corporation (the “Company”), that the Placement Agent shall serve as the exclusive placement agent for the Company, on a reasonable “best efforts” basis, in connection with the proposed offering (the “Placement”) of shares (the “Shares”) of common stock of the Company, par value $0.00001 per share (the “Common Stock”), and/or pre-funded warrants to purchase Shares (the “Pre-Funded Warrants” and together with the Shares, the “Securities”). The Securities actually placed by the Placement Agent are referred to herein as the “Placement Securities.” The Shares, Pre-Funded Warrants, and the shares of Common Stock underlying the Pre-Funded Warrants will be offered and sold under the Company’s registration statement on Form S-1 (File No. 333-281080). The documents executed and delivered by the Company and the Purchasers (as defined below) in connection with the Placement, including, without limitation, a securities purchase agreement (the “Purchase Agreement”), are collectively referred to herein as the “Transaction Documents.”

The terms of the Placement are to be mutually agreed upon by the Company and purchasers signatories to the Purchase Agreement (each, a “Purchaser” and collectively, the “Purchasers”), and nothing herein confers upon the Placement Agent the power or authority to bind the Company or any Purchaser, or constitutes an obligation for the Company to issue any Placement Securities or complete the Placement. The Company expressly acknowledges and agrees that the Placement Agent’s obligations hereunder are on a best efforts basis only and that the execution of this Agreement does not constitute a commitment by the Placement Agent to purchase the Placement Securities and does not ensure the successful placement of the Placement Securities, or any portion thereof, or the success of the Placement Agent with respect to securing any other financing on behalf of the Company. The Placement Agent may retain other brokers or dealers to act as sub-agents or selected-dealers on its behalf in connection with the Placement, subject to the approval of the Company, which shall not be unreasonably withheld. Certain affiliates of the Placement Agent may participate in the Placement by purchasing some of the Placement Securities. The sale of Placement Securities to any Purchaser will be evidenced by a Purchase Agreement between the Company and such Purchaser in a form reasonably acceptable to the Company and the Purchaser. Capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement. Prior to the signing of any Purchase Agreement, officers of the Company will be available to answer inquiries from prospective Purchasers.

Section 1. Representations and Warranties of the Company; Covenants of the Company.

(a) Representations of the Company. With respect to the Placement Securities, each of the representations and warranties (together with any related disclosure schedules thereto) and covenants made by the Company to the Purchasers in the Purchase Agreement in connection with the Placement, is hereby incorporated herein by reference into this Agreement (as though fully restated herein) and is, as of the date of this Agreement and as of the date of closing of the Placement (the “Closing Date”), hereby made to, and in favor of, the Placement Agent. In addition to the foregoing, the Company represents and warrants that there are no affiliations with any FINRA member firm participating in the Placement among the Company’s officers, directors or, to the knowledge of the Company, any five percent (5.0%) or greater securityholder of the Company. 

(b) Covenants of the Company. The Company covenants and agrees to continue to retain (i) an independent public accounting firm registered with the Public Company Accounting Oversight Board (“PCAOB”) for a period of at least three (3) years after the Closing Date and (ii) a competent transfer agent with respect to the Placement Securities for a period of three (3) years after the Closing Date. In addition, from the date hereof until thirty (30) days after the Closing Date, subject to certain exceptions provided for in the Purchase Agreement, neither the Company nor any Subsidiary shall issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents, except that such restriction shall not apply with respect to an Exempt Issuance (as defined in the Purchase Agreement). In addition, from the date hereof until thirty  (30) days after the Closing Date, neither the Company nor any Subsidiary shall effect or enter into an agreement to effect any issuance by the Company or any of its Subsidiaries of shares of Common Stock or Common Stock Equivalents (as defined in the Purchase Agreement) (or a combination of units thereof) involving a Variable Rate Transaction (as defined in the Purchase Agreement).

Section 2. Representations of the Placement Agent. The Placement Agent represents and warrants that it (i) is a member in good standing of the Financial Industry Regulatory Authority (“FINRA”), (ii) is registered as a broker/dealer under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the securities laws of each state in which an offer or sale of Placement Securities is made (unless exempt from the respective state’s broker-dealer registration requirements), (iii) is licensed as a broker/dealer under the laws of the United States of America, applicable to the offers and sales of the Placement Securities by the Placement Agent, (iv) is and will be a corporate body validly existing under the laws of its place of incorporation, and (v) has full power and authority to enter into and perform its obligations under this Agreement. The Placement Agent will immediately notify the Company in writing of any change in its status with respect to subsections (i) through (v) above. The Placement Agent covenants that it will use its reasonable best efforts to conduct the Placement hereunder in compliance with the provisions of this Agreement and the requirements of applicable law.

Section 3. Compensation. In consideration of the services to be provided for hereunder, the Company shall pay to the Placement Agent and/or its respective designees a cash fee of 2.5% of the aggregate gross proceeds raised from the sale of the Placement Securities (the “Cash Fee”). The Placement Agent reserves the right to reduce any item of compensation or adjust the terms thereof as specified herein in the event that a determination is made by FINRA to the effect that the Placement Agent’s aggregate compensation is in excess of that permitted by FINRA Rules or that the terms thereof require adjustment.

Section 4. Tail. Whether or not the Placement Agent consummates the Placement as contemplated by this Agreement, the Placement Agent shall be entitled to a cash fee equal to two and a half percent (2.5%) of the gross proceeds received by the Company from the sale of the Securities to any investor actually introduced by Placement Agent to the Company during the period from July 19, 2024, to the earlier of (i) September 2, 2024 or (ii) the Closing Date (the “Tail Financing”), and such Tail Financing is consummated at any time during the six (6) month period following the expiration of the Engagement Period, provided that such financing is by a party actually introduced to the Company by the Placement Agent in an offering in which the Company has direct knowledge of such party’s participation. The Placement Agent will provide the Company a list of all parties introduced to the Company. Any right to the fees provided by this paragraph shall be terminated upon termination of this Agreement by the Company for “Cause,” which shall mean a material breach by the Placement Agent of this Agreement or a material failure by the Placement Agent to provide the services as contemplated by this Agreement.

Section 5. Expenses. The Company agrees to pay all costs, fees and expenses incurred by the Company in connection with the performance of its obligations hereunder and in connection with the transactions contemplated hereby, including, without limitation: (i) all expenses incident to the issuance, delivery and qualification of the Placement Securities (including all printing and engraving costs); (ii) all fees and expenses of the registrar and transfer agent of the Shares; (iii) all necessary issue, transfer and other stamp taxes in connection with the issuance and sale of the Placement Securities; (iv) all fees and expenses of the Company’s counsel, independent public or certified public accountants and other advisors; (v) all costs and expenses incurred in connection with the preparation, printing, filing, shipping and distribution of the Registration Statement (including financial statements, exhibits, schedules, consents and certificates of experts), the Base Prospectus and each Prospectus Supplement, and all amendments and supplements thereto, and this Agreement; (vi) all filing fees, reasonable attorneys’ fees and expenses incurred by the Company in connection with qualifying or registering (or obtaining exemptions from the qualification or registration of) all or any part of the Placement Securities for offer and sale under the state securities or blue sky laws or the securities laws of any other country; (vii) the fees and expenses associated with including the Placement Securities on the Trading Market; and (viii) reasonable legal fees and disbursements for counsel to the Placement Agent, in an aggregate amount of up to $70,000; provided, however, that such amount in no way limits or impairs the indemnification and contribution provisions of this Agreement. In addition to the foregoing, the Company agrees to pay to the Placement Agent a non-accountable expense allowance in the amount of 1% of the gross dollar amount of the Placement.

Section 6. Right of First Refusal. Subject to the right of the Company to terminate this Agreement for cause pursuant to Rule 5110(g)(5)(B) of FINRA, the Company agrees that, if, for the period ending six (6) months from the consummation of the Placement, the Company or any of its subsidiaries (a) decides to dispose of or acquire business units or acquire any of its outstanding securities or make any exchange or tender offer or enter into a merger, consolidation or other business combination or any recapitalization, reorganization, restructuring or other similar transaction, including, without limitation, an extraordinary dividend or distributions or a spin-off or split-off, and the Company decides to retain a financial advisor for such transaction, the Placement Agent (or any affiliate designated by the Placement Agent) shall have the right to act as the Company’s exclusive financial advisor for any such transaction; or (b) decides to finance or refinance any indebtedness using a manager or agent, the Placement Agent (or any affiliate designated by the Placement Agent) shall have the right to act as sole book-runner, sole manager, sole placement agent or sole agent with respect to such financing or refinancing; or (c) decides to raise funds by means of a public offering (including through an at-the-market facility) or a private placement or any other capital-raising financing of equity, equity-linked or debt securities using an underwriter or placement agent, the Placement Agent (or any affiliate designated by the Placement Agent) shall have the right to act as sole book-running manager, sole underwriter or sole placement agent for such financing. If the Placement Agent or one of its affiliates decides to accept any such engagement, the agreement governing such engagement will contain, among other things, provisions for customary fees for transactions of similar size and nature and the provisions of this Agreement, including indemnification, which are appropriate to such a transaction.

Section 7. Lock-Up.

(a) The Company, on behalf of itself and any successor entity, agrees that, without the prior written consent of the Placement Agent, it will not, for a period of 30 days after the date of this Agreement (the “Lock-Up Period”), (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of capital stock of the Company or any securities convertible into or exercisable or exchangeable for shares of capital stock of the Company; (ii) file or caused to be filed any registration statement with the Commission relating to the offering of any shares of capital stock of the Company or any securities convertible into or exercisable or exchangeable for shares of capital stock of the Company, other than the Pricing Prospectus, a Prospectus Supplement or filing a registration statement on Form S-8 in connection with any employee benefit plan or amendments or supplements to registration statements; (iii) complete any offering of debt securities of the Company, other than entering into a line of credit with a traditional bank or (iv) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of capital stock of the Company, whether any such transaction described in clause (i), (ii), (iii) or (iv) above is to be settled by delivery of shares of capital stock of the Company or such other securities, in cash or otherwise.

(b) Schedule I hereto contains a complete and accurate list of the Company’s directors and officers (collectively, the “Lock-Up Parties”). The Company has requested that each of the Lock-Up Parties deliver to the Placement Agent an executed Lock-Up Agreement substantially in the form of Exhibit A hereto (each, a “Lock-Up Agreement”), on or prior to the date of this Agreement. The Placement Agent may, in its sole discretion, agree to waive and release any director or officer of the Company from the restrictions of the Lock-Up Agreement to which one or more of them is party and provide the Company with notice of the impending release or waiver substantially in the form of Exhibit B hereto at least three (3) Business Days before the effective date of the release or waiver. In such case, the Company agrees to announce the impending release or waiver by a press release substantially in the form of Exhibit C hereto through a major news service at least two (2) Business Days before the effective date of the release or waiver.

Section 8. Indemnification.

(a) To the extent permitted by law, with respect to the Placement Securities, the Company shall indemnify the Placement Agent and its affiliates, stockholders, directors, officers, employees, members and controlling persons (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) against all losses, claims, damages, expenses and liabilities, as the same are incurred (including reasonable actual and documented fees and expenses of counsel), caused by, or arising out of or in connection with, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Incorporated Document, or any Prospectus or by any omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading (other than untrue statements or alleged untrue statements in, or omissions or alleged omissions from, information relating to an Indemnified Person furnished in writing by or on behalf of such Indemnified Person expressly for use in the Incorporated Documents). Notwithstanding anything set forth herein to the contrary, the Company agrees to indemnify the Placement Agent, to the fullest extent set forth in this Section 8, against any and all claims asserted by any or person or entity alleging that the Placement Agent was not permitted or entitled to act as a placement agent herein, or that the Company was not permitted to hire or retain the Placement Agent herein, including but not limited to any claims arising out of any purported right of first refusal another person or entity claims to have to act as a placement agent or any similar role with respect to the Company or its securities.

(b) Promptly after receipt by the Placement Agent of notice of any claim or the commencement of any action or proceeding with respect to which the Placement Agent is entitled to indemnity hereunder, the Placement Agent will immediately notify the Company in writing of such claim or of the commencement of such action or proceeding, but failure or delay of notification to so notify the Company shall not relieve the Company from any obligation it may have hereunder, except and only to the extent such failure results in the forfeiture by the Company of substantial rights and defenses or materially adversely impacts the Company. If the Company so elects or is requested by the Placement Agent, the Company will assume the defense of such action or proceeding and will employ counsel reasonably satisfactory to the Placement Agent and will pay the fees and expenses of such counsel. Notwithstanding the preceding sentence, the Placement Agent will be entitled to employ its own counsel separate from counsel for the Company and from any other party in such action if counsel for the Placement Agent reasonably determines that it would be inappropriate under the applicable rules of professional responsibility for the same counsel to represent both the Company and the Placement Agent. In such event, the reasonable fees and disbursements of no more than one such separate counsel will be paid by the Company, in addition to fees of local counsel. The Company will have the right to settle the claim or proceeding, provided that the Company will not settle any such claim, action or proceeding without the prior written consent of the Placement Agent, which will not be unreasonably withheld. The Company will not be liable for settlement of any action effected without its written consent, which may not be unreasonably withheld, conditioned or delayed.

(c) The Company agrees to notify the Placement Agent promptly of the assertion against it or any other person of any claim or the commencement of any action or proceeding relating to a transaction contemplated by this Agreement.  

(d) If for any reason the foregoing indemnity is unavailable to the Placement Agent or insufficient to hold the Placement Agent harmless, then the Company shall contribute to the amount paid or payable by the Placement Agent as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand and the Placement Agent on the other, but also the relative fault of the Company on the one hand and the Placement Agent on the other that resulted in such losses, claims, damages or liabilities, as well as any relevant equitable considerations. The amounts paid or payable by a party in respect of losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees and expenses incurred in defending any litigation, proceeding or other action or claim. Notwithstanding the provisions hereof, the Placement Agent’s share of the liability hereunder shall not be in excess of the amount of fees actually received, or to be received, by the Placement Agent under this Agreement (excluding any amounts received as reimbursement of expenses incurred by the Placement Agent).

(e) The provisions of this Section 8 will remain in full force and effect, survive the expiration or termination of this Agreement, and be in addition to any liability that the Company might otherwise have to any indemnified party under this Agreement, whether or not the transaction contemplated by this Agreement is completed.

Section 9. Engagement Term. The Placement Agent’s engagement hereunder will be until the earlier of (i) _________, and (ii) the Closing Date (such earlier date, the “Termination Date”), unless otherwise extended by the parties in writing; provided, however, the Placement Agent may terminate this Agreement prior to the Termination Date if it reasonably determines that it is unsatisfied with the results of its due diligence investigation, notwithstanding its best efforts to complete the Placement. Notwithstanding anything to the contrary contained in this Agreement, in the event that the Placement pursuant to this Agreement shall not be carried out for any reason whatsoever during the Term, the Company shall be obligated to pay to the Placement Agent its actual and accountable out-of-pocket expenses related to the Placement (including the fees and disbursements of the Placement Agents’ legal counsel), up to a maximum of $30,000 and, if applicable, for electronic road show service used in connection with the Placement. The Placement Agent may not use any confidential information concerning the Company provided by the Company for any purposes other than those contemplated under this Agreement.

Section 10. Placement Agent Information. The Company agrees that any information or advice rendered by the Placement Agent in connection with this engagement is for the confidential use of the Company only in their evaluation of the Placement and, except as otherwise required by law, the Company will not disclose or otherwise refer to the advice or information in any manner without the Placement Agent’s prior written consent.

Section 11. No Fiduciary Relationship. This Agreement does not create, and shall not be construed as creating rights enforceable by any person or entity not a party hereto, except those entitled hereto by virtue of the indemnification provisions hereof. The Company acknowledges and agrees that the Placement Agent is not and shall not be construed as a fiduciary of the Company and shall have no duties or liabilities to the equity holders or the creditors of the Company or any other person by virtue of this Agreement or the retention of the Placement Agent hereunder, all of which are hereby expressly waived.

Section 12. Closing. The obligations of the Placement Agent, and the closing of the sale of the Placement Securities hereunder are subject to the accuracy, when made and on the Closing Date, of the representations and warranties on the part of the Company contained herein and in the Purchase Agreement, to the performance by the Company of its obligations hereunder and in the Purchase Agreement, and to each of the following additional terms and conditions, except as otherwise disclosed to and acknowledged and waived by the Placement Agent:

(a) All corporate proceedings and other legal matters incident to the authorization, form, execution, delivery and validity of each of this Agreement, the Placement Securities, and all other legal matters relating to this Agreement and the transactions contemplated hereby with respect to the Placement Securities have been completed or resolved in a manner reasonably satisfactory in all material respects to the Placement Agent. 

(b) The Placement Agent has received from outside legal counsel to the Company such counsel’s written opinion and negative assurance letter with respect to the Placement Securities, addressed to the Placement Agent and dated as of the Closing Date, in form and substance reasonably satisfactory to the Placement Agent.

(c) The Placement Agent has received customary certificates of the Company’s executive officers (the “Officer’s Certificate”) as to the accuracy of the representations and warranties contained in the Purchase Agreement, and a certificate of the Company’s secretary (the “Secretary’s Certificate”) certifying (i) that the Company’s organizational documents are true and complete, have not been modified and are in full force and effect; (ii) that the resolutions of the Company’s Board of Directors relating to the Placement are in full force and effect and have not been modified; and (iii) as to the incumbency of the officers of the Company. Each of the Officer’s Certificate and Secretary’s Certificate must be dated as of the Closing Date, and all documents referenced in the Secretary’s Certificate must be attached thereto.

(d) The Common Stock has been registered under the Exchange Act and listed, admitted and authorized for trading on the Trading Market or other applicable U.S. national exchange as of the Closing Date, and the Placement Agent has received reasonably satisfactory evidence of such actions. The Company has not taken any action designed to, or likely to have the effect of terminating the registration of the Common Stock under the Exchange Act or delisting, or suspending from trading, the Common Stock from the Trading Market or other applicable U.S. national exchange. The Company has not received any information suggesting that the Commission or the Trading Market or other U.S. applicable national exchange is contemplating terminating such registration or listing.

(e) No action or proceeding before a court of competent jurisdiction has been taken, and no statute, rule, regulation or order has been enacted, adopted or issued by any governmental agency or body that would, as of the Closing Date, prevent the issuance or sale of the Placement Securities or materially and adversely affect the business or operations of the Company. No injunction, restraining order or order of any other nature by any federal or state court of competent jurisdiction has been issued as of the Closing Date that would prevent the issuance or sale of the Placement Securities or materially and adversely affect the business or operations of the Company.

If requested by the Placement Agent, the Company has filed, or has authorized the Placement Agent’s counsel to file on the Company’s behalf, with FINRA all necessary materials in compliance with FINRA Rule 5110 with respect to the Placement and has paid all filing fees required in connection therewith.

(h) The Placement Agent has received an executed Lock-Up Agreement from each of the Company’s officers and directors prior to the Closing Date.

(i) On or before the Closing Date, the Placement Agent and counsel for the Placement Agent have received such information and documents as they may reasonably require for the purposes of enabling them to pass upon the issuance and sale of the Placement Securities as contemplated herein, or in order to evidence the accuracy of any of the representations and warranties of the Company, or the satisfaction of any of the conditions or agreements, herein contained. 

(j) On the date hereof, the Placement Agent shall have received, and the Company shall have caused to be delivered to the Placement Agent, a letter from Bush & Associates CPA LLC, the independent registered public accounting firm of the Company (the “Auditor”), addressed to the Placement Agent, dated as of the date hereof, in form and substance satisfactory to the Placement Agent. The letter shall not disclose any change in the condition (financial or other), earnings, operations or business of the Company, which, in the Placement Agent’s sole judgment, is material and adverse and that makes it, in the Placement Agent’s sole judgment, impracticable or inadvisable to proceed with the Placement of the Securities.

(k) On the Closing Date, the Placement Agent shall have received from the Auditor a letter, dated as of the Closing Date, to the effect that the Auditor reaffirms the statements made in the letter delivered pursuant to Section 12(j) hereof.

If any of the conditions specified in this Section 12 have not been fulfilled when and as required by this Agreement, the Placement Agent may terminate this Agreement at any time on or prior to the Closing Date by giving oral or written notice to the Company. Any such oral notice must be promptly confirmed in writing.

Section 13. Governing Law. This Agreement will be governed by, and construed in accordance with, the laws of the State of New York applicable to agreements made and to be performed entirely in such State. This Agreement may not be assigned by either party without the prior written consent of the other party. This Agreement is binding upon, and inure to the benefit of, the parties hereto and their respective successors and permitted assigns. Any right to trial by jury with respect to any dispute arising under this Agreement or any transaction or conduct in connection herewith is waived. Any dispute arising under this Agreement may be brought into the courts of the State of New York or into the federal court located in the City and County of New York, and, by execution and delivery of this Agreement, the Company hereby accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of aforesaid courts. Each party hereto irrevocably waives personal service of process, consents to process being served in any such suit, action or proceeding by delivering a copy thereof via overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement, and acknowledges that such service will constitute good and sufficient service of process and notice thereof. If either party commences an action or proceeding to enforce any provisions of this Agreement, then the non-prevailing party in such action or proceeding shall reimburse the prevailing party for its attorney’s fees and other costs and expenses incurred in connection with such action or proceeding.

This Agreement may not be amended or otherwise modified or waived except by an instrument in writing signed by both the Placement Agent and the Company. The representations, warranties, agreements and covenants contained herein shall survive the Closing Date of the Placement and delivery of the Placement Securities. This Agreement may be executed in two or more counterparts, all of which, when taken together, will be considered one and the same agreement. This Agreement will become effective when each party hereto has received a counterpart hereof signed by the other party. In the event that any signature is delivered by facsimile transmission or a .pdf format file, such signature will create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or .pdf signature page were an original thereof.
